Review on ASRock B450M PRO4 AM4 AMD Promontory B450 Motherboard: Enhanced Performance with SATA 6Gb/s, USB 3.1, HDMI, Micro ATX by Chae Hahm ᠌

Pros below: Rev.4 from the store was flashed with bios p32022 (I took it in two different places), Ryzen 3 3200G wound up without dancing with a tambourine. The CMW16GX4M2C3000C15 memory started up by default at a low frequency, but the 3000 profile is easily selected in the BIOS without the need to manually set the latency and voltage. Three types of video outputs (VGA / DVI / HDMI) allow you to use old, but still alive, monitors for a long time. Has some cons This can hardly be considered a disadvantage, but if you take a board for experiments with overclocking, then it is probably worth looking at other options. Raising the base frequency of the system bus by 1MGz disabled the USB3 controller. I have not experimented with the second board - it works fine :)
